Automotive 12V batteries typically operate in the range of 9V-16V. However this voltage can vary widely due to transient conditions such as cold crank and load dump. This reference design creates a well-regulated 25W (5V,5A) output, regardless of large input voltage transients, utilizing the LM5150-Q1 and LM5141-Q1. The LM5150-Q1 is implemented as a pre-boost, only switching when the input voltage is below 6.8V, and utilizes the inductor as a differential EMI filter when not switching. The LM5141-Q1 operates as a buck controller regulating the 5V output. Both devices switch at 2.2 MHz.
